Use this task when completing your Configuration Worksheets prior to the SuperCluster installation.
Every CMIOU has 16 memory slots.
• SuperCluster M8 – Each CMIOU is fully populated with 64 GB DIMMs, for a total of 1 TB (1024 GB) of memory in each CMIOU, with 960 GB available after DIMM sparing.
• SuperCluster M7 – Each CMIOU is fully populated with 32 GB DIMMs, for a total of 512 GB of memory in each CMIOU, with 480 available after DIMM sparing.
Refer to the applicable Domain Specifications in these sections:
Enter the amount of memory for each domain in the Configuration Worksheet.
Example
For a U2-2 domain configuration (two domains in a PDomain). by default, 50% of the memory resources are assigned to each domain. Alternatively, you can specify different values for each domain, such as 60% of the memory resources to the first domain and 40% to the second domain.
In this example, the total memory resources for SuperCluster M8 with a U2-2 configuration is 1.92 TB. A 60% / 40% configuration allocates these CPU resources (values are rounded):
Domain 1 – 1.15 TB
Domain 2 – 768 GB
Enter the memory resources for each zone in the Configuration Worksheet.
Example
The first domain is a Database Domain that will contain four equal-sized zones.
Domain 1 has 1.15 TB of memory. 1.15 / 4 = 480 GB per zone.
Enter the memory resources for each I/O Domain in the Configuration Worksheet.
Example:
The second domain is a Root Domain that will support four equal-sized I/O Domains.
Domain 2 has 768 GB of memory. Subtract 32 GB (minimum required) for the Root Domain itself. That leaves 736 GB for I/O Domains. 736 / 4 = 184 GB of memory per I/O Domain.
